Re: old cameras and personal film speed
Ahhhhh..... just what you need. A new camera/style in the middle of your
zone system/film development madness ;-)
Zone plates are a variation on pinholes. Instead of one tiny hole, think of
an archary target. The center hole and all of the "white" circles let in
light, the "Black" circles don't. What you get is an image part pinhole and
part soft focus lens.
I don't have any of mine up on my website (my zoneplate work is more
play/diversion), but the links below will give more info.
The advantage of converting a "Lubitel" type twin lens camera, is that you
still have the "viewing" lens to line up your image. Zone plates aren't as
"slow" as pinholes, but they are still in the F64 area. Much too small to
easily "view". I wouldn't bother converting a camera with known shutter
problems (such as your Lubitel)!
